Bill,

There are two sources of easy-to-access info that I know about.

1) Photography with Emulsions, by W. Abney, 1885, starting on page 114. It's available as a Google book from the TLF lit list, #5: http://thelightfarm.com/Map/Literatu...eListPart1.htm

2) Wall's 1929 Photographic Emulsions. p.162.

And, though I feel like a broken record, I don't support the use of a surfactant in emulsions coated on glass. The times I tried were the only times my coating failed miserably. You're not using gelatin, so of course your situation might be different, but a reminder anyway.
